MACHINE FOR APPLYING TOGGLES T0 SKINS.

Application filed September 29, 1914.

ing Tog les to Skins, of which the following C3 is a specification, reference being had therein to the accompanying drawings.

My invention has for its. object an improvement on the machine for applying toggles to skins and the like shown and described in my prior application filed May 15, 1914, Ser. No. 838,868.

The particular object of my present invention is to secure a greater uniformity and certainty of operation of the machine and it consists particularly in combining with the parts shown in my prior application automatic means for supporting the toggle which is to be applied to the skins, and means for preventing the toggles in the raceway moving down except when the opening in the raceway is bridged.

The invention will be fully understood from the following description taken in connection with the accompanying drawings and the novel features thereof will be pointed out and clearly defined in the claims at the close of the specification.

Referring now to the drawings,-Figure 1 is a front elevation of the machine embodying my present invention. Fig. 2 is an end view of the machine shown in Fig. 1, the parts being in the position occupied by them before the toggle is closed onto the skin. Fig. 3 is an enlarged view of the parts shown in Fig. 1 illustrating the position occupied by the parts when the treadle is depressed. Fig. 4: is a section taken on line H of Fig. 3. Fig. 5 shows the toggle intended to be applied by my machine.

In the drawings, there is shown at A the frame, and at B the raceway of the machine.

At C C is shown a series of toggles in the raceway, the lowest toggle being designated D and being at the opening in the raceway, this being the point at which it is attached to the skin.

At E is shown the finger which engages the lever of the toggle and closes the toggle on the skin. The finger E is operated by a treadle 11 pivoted at 12 to the frame of the machine. Connected to the rear end of the treadle, is a link 13 which engages the lever Specification of Letters Patent.

and connected by a link 16 to the finger E.

It will therefore be seen that when the treadle 11 is depressed the finger E is raised to close the toggle. The treadle is returned to its original position by a counter weight 30. The lov'vermost toggle D as it moves out down the raceway across theopening in the raceway is supported on one end of a slide 17 operating in ways 18. The slide 17 is provlded with a pin 19 engaged by a fork formed on one end of a bell crank 20 pivoted at 21 to the frame of the machine. The other end of the bell crank is also forked and engages a pin 22 projecting from the side of the link 16. It will therefore be seen that, when the treadle isdepressed, the bell crank 20 operates to pull the slide 17 out from under the toggle D which has just passed out of the raceway into position to be applied to the skin. The toggle then rests with its two side edges a a on two small ledges f and 9, one of which is formed in the end of the lower member of the raceway and the other is formed in the wall opposite the end of the raceway.

At 23 is shown a stop slidable vertically in a hole in the frame A of the machine. This stop is reciprocated vertically by a lever 24 pivoted at 25, and connected by a link 26 to a rod 27 which projects sidewise from the treadle 11. When the treadle is pressed down the stop is pushed up. When the treadle is released the stop drops to its previous position. The upper end of the stop when in its raised position is above the lower edge of the sides a a of the lowermost toggle in the raceway so that the row of toggles filling the raceway are prevented from crowding against the toggle D which is in position to be secured to the skin.

The operation of my machine is as follows ;The toggles are placed in the raceway and are allowed to slide down until of toggles cannot move down while the toggle which is at the opening in the raceway is being attached to the skin. When the treadle is released, the stop moves out of contact with the toggle and allows the row of toggles to feed down ready for the next operation of the machine, The slide 17 re turns to its position bridging the opening in the raceway before the stop releases the other toggles in the raceway, so that the toggles cannot feed down until the opening has been bridged. When the toggle has been closed onto the skin, it-n'iay readily" be pulled out of the machine, because the lever oi the toggle is then up out of the way, and the toggle and its string are pulled forward through theopening in the raceway.

What I claim is:

1. fhe improved machine for" applying toggles to skins which'consists in a raceway capable of supporting; a series of toggles, a finger to'engage the lever of thetoggle,

and forcibly close the toggle on the skin,

operating mechanism for said finger and a' movable support for thesaid toggle, andmeans for 'moving the lever and simultaneously therewith withdrawing the support from under the toggle.

in a raceway capable of supporting a se ries of toggles, a finger to engage the lever of the toggle, a stop to engage the toggle in the raceway next the toggle to be ap plied to the skin said stop being operatively connected so that when the finger is being moved back after closing the toggle onto the skin the stop will be withdrawn from contact with the toggles, and permit the toggles to slide down the raceway.

3. The improved machine for applying toggles to skins which consists in a raceway having at its lower end an opening, there being supporting ledges for the toggle on opposite sides of the opening" in the raceway', a finger" to engage the" lever of the toggle and forcibly close it on the skin,- operating mecl'i'anism lor the said finger, a slide bridging the opening in the raceway and to permit the" lowest toggle to slide across the opening until its' sides rest on the said ledges, and means to withdraw the slide. v

In testimony whereof I affix my signature in presence of two witnesses.
